Last week, we wrote about this topic with respect largely to the things we drop in the water. So, what about the things we bring out there, like our copper-oxide bottom paint? This column is about that.Painting With PoisonYes, if you really think about it, we paint the bottoms of our boats with poison. Intentionally. We’re trying to kill barnacles, algae, slime, and other stowaways who can clog our intake valves, foul our running gear and, as a consequence, actually create another bio-hazard as we have to apply more power (meaning burning more fuel and creating more exhaust) to move the boat at a given speed. So, our intentions are not necessarily ignoble — but if we start to address some of the collateral damage, we can make them noble.The history of the War of the Barnacles goes back to the Phoenicians. They used many substances — including lead and tar — to battle the speed-killing and weight-adding stowaways. It wasn’t until the Romans realized that shields of battle work at sea too — and shielded their ships with copper sheathing — that something effective began to turn the battle in favor of the mariners. This technique lasted for millennia. History tells us that Nelson had an inherent 20-percent speed advantage over the Spaniards at the Battle of Trafalgar because of copper sheathing.A lot of dangerous things don’t reach the tipping point until there is a negative impact on the environment. By the 1950s, boating had begun to be popular enough that scientists started to notice that shellfish were being affected by these bottom paints. This started the process that more than a half-century later is showing up in various alternatives.Two Pounds A YearA 30-foot boat, painted with copper-oxide anti-fouling paint, leaches two pounds of copper into the waterways. Each year. Now, before you start to feel like an environment killer, scientists note that Nature naturally leaches 250,000 tons of copper into the sea each year — compared to the approximately 15,000 tons that all the sea-going vessels add. But the ocean is one thing, a marina with 100 vessels closely packed is another. And that is the rub, sort to speak.States and municipalities are starting to notice and taking action in two ways: restricting boat owners from using certain bottom paint mixtures, and keeping marina owners from draining their waste water into the sea. Connecticut banned marina owners from doing so a few years back, requiring them to collect the water and bring it to a treatment plant. Sounds expensive, which just ends up in dockage fees or, worse, fees so high that boaters start to drop out. Eventually, the Feds will bring a suit under the Clean Water Act and then the game is afoot.But the regulators aren’t just throwing (your) money at the problem. They are sponsoring “bake-offs” where boat owners and paint companies can try different formulas to address the issue. San Diego both passed a law that requires the amount of copper pollution in the Port of San Diego to be reduced by 75 percent in 15 years and has created test beds for various formulas. And they have found that not only are different chemicals effective (such as zinc) but also paints can be made slicker so those stowaways can’t grab a toe-hold (or whatever it is that they hold on with!)The paint companies haven’t sat on their hands and have developed a number of alternatives, but getting approval from the EPA to add a chemical to the equation takes considerable time too. Will the solutions cost more? They already do and they will continue to. Not sure there is any way around that one.A Primer Of SortsThere is a lot of material out there and you can always discuss it with your dock master, who is certainly interested in the health of our waterways. The largest anti-fouling paint company, InterLux, maintains a lot of material online (www.yachtpaint.com).For the more scientifically inclined, the stowaways are not attaching to our boats for a ride. They attach to eat. When you put anything in water, tiny electrical charges develop. This was discovered by Johannes van der Waals 1873 (getting the Nobel Prize in 1910.) Via the “van der Waals” force, free-floating objects are attracted to the surface of that object. In waterways, these objects are decaying matter, a very attractive food source to our stowaways. The table is set. All it needs is hungry guests, which Mother Nature serves up readily.By the way, if you are interested in being part of USCG Forces, email me at JoinUSCGAux@aol.com or go direct to the D1SR Human Resources department, who are in charge of new members matters, at DSO-HR and we will help you “get in this thing . . .” Share

Magnone has more than 20 years of experience in the heavy equipment logistics industry and Skelton Sherbornedirector Brad Skelton said it is an excellent move for the company.Skelton said: “Julie has been at Skelton Sherborne for 14 years, starting in freight operations as a consultant. She quickly proved herself and was promoted to acquisitions manager, general manager and COO before moving into this new job.”We are very happy that Julie has accepted the role. She has already been fulfilling many of the responsibilities of CEO and I’m confident she will enhance the position Skelton Sherborne already occupies in the market.”Magnone’s promotion to CEO will allow Skelton to focus on other initiatives. The position of COO will be filled by Bob Gairdner. He has 22 years of experience in the road transport and air freight industries.Meanwhile, in its latest Shipping Index, for February 2012, the company notes that Australian machinery import volumes in February decreased by 21 percent overall to 4,511 units, though this included some normalisation of apparent exaggerated tracked crane data in January.The figures are still buoyed in the area of “road making, paving and other public works equipment”. The Tariff item that these goods are classified under includes smaller commercial machines which may have been imported in bulk during the current period. By excluding the particular Tariff item volumes, it can be noted that the number of other “heavy” equipment machines has decreased 9 0.000000or February from 2,426 to 2,200 units.www.skeltonsherborne.com

CHINA: A ceremony at Golmud in Qinghai province during October officially launched construction of a 506 km railway to Dunhuang in Gansu province. Work is expected to take five years and cost 12·9bn yuan.The single-track electrified line with provision for future doubling will provide a connection between the existing railway to Tibet and the line to Xinjiang. It is being designed for 160 km/h running and freight trains of up to 4000 tonnes. A service of 20 pairs of passenger trains a day is planned, and freight traffic is predicted at 60 million tonnes/year. Studies were undertaken to ensure the railway would not be at risk from sand blown from ‘megadunes’ along the route.
Author: Priyanka Ann Saini On October 20, Scorpio Bulkers Inc. announced that it has entered into a financing transaction in respect of one of the Company’s Kamsarmax vessels with unaffiliated third parties in Japan.The cost of the financing is equivalent to an expected fixed interest rate of 4.24% for 10 years. If converted to floating interest rates, based on the expected weighted average life of the transaction, the equivalent margin at current swap rates would be LIBOR + 2.07%.As part of the transaction, the Company will sell a 2015 Japanese built Kamsarmax dry bulk vessel, SBI Rumba, for a consideration of approximately USD 19.6 million and then lease it back from the buyers through a 9.5 year bareboat charter agreement, with the Company’s option to extend for a further six months.The agreement also provides the Company with options to repurchase the vessel beginning on the fifth anniversary of the sale and until the end of the bareboat charter agreement. This transaction, which shall be treated as a financial lease for accounting purposes, increases the Company’s liquidity by approximately USD 6.0 million, net of commissions and after repayment of the vessel’s existing loan.Sea News, October 23
Share General Secretary of the Dominica Public Service Union (DPSU), Thomas Letang (file photo)The Dominica Public Service Union (PSU) has extended Christmas greetings to all Public Servants represented it represents and to the general public.In his 2015 Christmas address, General Secretary of the Union, Thomas Letang urged Dominicans to let this Christmas, on the heels of Tropical Storm Erika, signal “the beginning of life in which we will not fail to love, forgive and share with our fellow citizens”.Here is Mr Letang’s message;“And the angel said unto them fear not for behold I bring you good tiding of great joy which shall be to all people for unto you is born this day in the city of David a savior which is Christ the lord and this shall be a sign unto you. You shall find the baby wrapped in swaddling clothes lying in a manger. What a humble birth for the King of Kings and Lord of Lords our savior and redeemer.In celebrating the birth of Christ we must be Mindful of his many great teachings. For, example he says to us that whatever we do to the least of our brothers that we do unto him. He exports us that he who has two coats should impart to him who has none, and he who has two mittens should do likewise.To only give at Christmas when we could have reached out to the less fortunate brothers and sisters on other occasions is rather unfortunate. Did we clothe the naked when they needed us? Where the hungry fed when their tummy’s ached? Did we provide shelter to those who were exposed to the elements? Have we built a vocation of visiting the sick and bed ridden or do we always wait for this season every year to do so?Whatever form of kindness we are bestowing this season we should continue to do so beyond the Christmas celebrations. Our lord whose birth we celebrate has promised that he will be with us through good times and bad times his blessing are not for just one day even when we stray from his path he has not abandon us.On behalf of the entire Dominica Public Service Union Family I wish all Dominicans a Merry and Spiritual Christmas and health and prosperity.
